I love OGA! Here's an issue I encountered. Please let me know if it's a bug or if I'm just doing it wrong:

Browsing for Music, I enter tags of "space background" (no quotes, no punctuation). Nothing comes up. When looking through all the tracks, there definitely are files with 'space' and 'background' tags. I tested with 'is one of' and 'is all of'.

Also, I'd request changing 'is one of' to 'is any of'.

Thanks for providing such a great resource!
